While maintaining an old MFC application we have implemented a new progress dialog bar in WPF. The application currently has the UI thread busy with a lot of business operations but changing this is out of scope.

When a string property changes its value (binded to the text of a TextBox) the progress dialog does not get refreshed (only sometimes when the thread is not so busy).

As far as I know as the update of the property is done from the UI thread the thread should be able to update the dialog and repaint it before going on the next thing so I don’t get why it’s not being updated and how to fix it.

Any ideas?

EDIT: What are the drawbacks of this solution, I have tried it and seems to work fine:

private static Action EmptyDelegate = delegate() { };

public static void Refresh(this UIElement uiElement)
{
   uiElement.Dispatcher.Invoke(DispatcherPriority.Render, EmptyDelegate);
}
